Civic associations are expected to foster civic, pro-social behavior, but this optimistic view is increasingly contested. We argue that populist radical right parties can strategically target and infiltrate associations to diffuse anti-establishment rhetoric and anti-democratic attitudes. We illustrate this phenomenon by examining the relationship between civic associations and compliance with government rules during Germany's first Covid-19 lockdown with a difference-in-differences design. Results show that areas with denser sport, nature, and culture clubs recorded higher mobility under lockdown. We document the infiltration mechanism and the spreading of anti-democratic attitudes within associations, using survey and election data and qualitative evidence including interviews. In doing so, we shed light on a negative effect of social networks and an understudied strategy of challenger populist parties.

Using data from the World Values Survey, we analyze the extent to which value consensus exists within countries. To do this, we introduce a statistical model which allows us to generate country-level measures of cultural heterogeneity. Our statistical approach models each country as a mixture of subcultures that are shared across the world. Our results demonstrate that value consensus varies substantially across countries and regions.
